Abstract (en)
[origin: EP2597696A1] An object of the invention is to provide an organic EL element formed using a relatively stable new electron injection material in an atmosphere of approximately ordinary pressure. An organic EL element of a preferable embodiment is an organic EL element including a supporting substrate, an anode, a light-emitting layer, an electron injection layer, and a cathode in this order, in which the electron injection layer is formed by applying an ink including an ionic polymer so as to form a film, and the cathode is formed by applying an ink including a material which forms the cathode so as to form a film or transferring a conductive thin film which forms the cathode.
